.T0 all fio/wm it may concern Be it known that lf, JOHN C.v ENoLsn, a citizen ot the United States, and a resident of Camden, in "the county ot' Camden and State oit New Jersey, have invented certain new and useful improvements in Tone- .drrns for Talking-Machines, whereof the following is a specification, reference being had to the accompanying drawings.

This invention particularly relates to the with the swinging tone arm of a talking machine.

The principal objects of this invention are, to provide a simple and ellicient mounting for connectingthe tone arm and sound reproducer, which is cooperative with said arno when said reproducer is in operative position to alord a smooth, uninterinpted, continuous conduit for the :tree passage of sound Waves; structure which when in inoperative position may he inclosed in a minimum space.

Further objects of this invention are toprovide such a pivoted connection between said tone arm and sound .reproducer as to permit the free movement of said reproducer relative to'said arm, effected 'by possible slight irregularities in the record disk, and to permit the .movement of said repro ducer from said record to its inoperative position; to provide means carried oy said arm to support said reprodueer in an approzriniately operative position, independently of the turn-table oi said talking maplaine; to provide means to support said sound reproducer in its inoperative posit-ion at the side ot said arm, and extending below the top' thereof; and to provide means to automatically close said conduit when said sound reprodueer is disposed in its inoperainvention hereinafter hollov7 tapered tone The forni or the described provides a arm suitably mounted st-antially vertical axis, and having its free end curvedflatera-llyend terminating` in a flanged collaryto which is pivoted a sind lar flanged collar on the tubular mounting, upon the free nend of which the sound reprodneer is reino lately attached. of the mounting isi provided with a 'lug or hook operative to engage suitably disposed lugs on the ilange oi said arm and respeevelevational vien7 and to provide a compact sitiong Fig. 5 is a plan view' to swing on a sub-` Y and 2G, which The flange' tively arranged to support the sound reproand in its inoperative position.

This invention further includes all of th various novel features of construction and arrangement hereinafter more definitely specified. A

1n the accompanying drawings, Figure l is a fragmentary sectional elevation of a talking machine, showing the tone arm carrying a sound reprod-ucer in operative relation to a sound record disk; Fig', 2 is a fragmentary plan sectional "view of the structure shown in Fig. i.; Fig. 3 is a side of said tone-erin support ing the reproducer in an approximately operative `osition7 inde endently ofthe sound D P record disk; Fig. el. is a .fragmentary View similar to Fig. 3, but showing thev sound reproducer inverted to its inoperative poof the structure as shown in Fig. t, exclusive of the easing; and Fig. 6 is a perspective view of the sound reproducer mounting per Se.

ln said figures, the tone armf is mounted to swing in a vplane substantially parallel with the turn-table 8, upon the trunnions 9 and 10, which are respectively supported in hearings 11 and 12 in a Well-known manner. Said tone arm 7 is preferably tapered throughout 'its extent and has its free end 14 curved laterally, and terminating in a flanged collar 15, which is provided with a hose 16, having a threaded aperture 17 disposed at one side of the end of the tone arm, arranged to receive the pivot lpin 18, upon which the sound reproducer mounting` 20 is swiveled. Said mounting 20 is preferably provided with a flanged collar 21,. which is similar to collar 15 onthe tone arm 7, and which is provided with a boss 22 having an aperture 23 through which the pivot pin 18 extends. V

As cest shown in Figs. 1, 3 and et, the flanges 15- and 21 each have an impcrforate extension, eccentric to the respective-open ings therethrough, and the flange 15 is provided witli suitably disposed peripheral lugs are respectively provided with projections 27 and 28, extending from the face of said plate and arranged to be engaged by a peripheral hook or lug 30 on the flange 21. y As best Vshown in Figs. 4 and 5, the pro jpction 27 is arranged to supportI the sound reproducer 32 in its inoperative position, spaced from theside of the interinediate portion of the tone' arm 7 and inclose proximity to the turn-table S, so as to be supported substantially below the upward extension ot' 4the tone arm support, the axis of said sound i reproducer 32 being disposed substantially 'in a plane Vwith the axis of the straight in.-

terinediate portion of the tone arm 7. rllhe -projection 28 is arranged to support said Sound repreducer 32 in an approximately operative position, independently of a sound I record dislr 3l, or its supporting` turn-table 8, as shown in Fig.v 3.

The sound reproducer 32 may be suitably vformed by the cooperation of the sound ref' .producer mounting 20 with the tone arm 7,

whenin registry, .pro vides a smooth, regular passageway, substantially in the. form 'of an ogee curve, free from pockets or other` eddy-producing obstructions.

lReferring again to Fig. 2, it will be seen that by the construction contemplated, the sound'reproducer 32, when inverted to its -inoperative position, may be swung to such a 'lateral position with respect to the tone arm 7, that its upwardly extending extremities .are substantially below. or on a level' with the supporting' members of said tone arm.' Thus it will be seen that. the-mechanisin may be inclosed in a smaller space than Whenthesound reproducer rests upon the tone arm Y when in its inoperative position. Therefore, it will also be obvious that the lid or cover 35 may be disposed in closer relation to the turn-table 8 of the machine than in machines heretofore constructed, whereby the height'of'the machine may be materially reduced. I

Referring to Figs. 4 `and 5, it will be noted that the conduit formed by the cooperation of the mounting,` 2O andthe tone arm 7 is closed by the imperforate eccentric portions of the respective flanges l5 and 23, when the Sound reproducer is disposed in its inoperative position', so as' to prevent the entrance of dust into-said conduit..

It isv not desired to limit this inventionto thofprecise' details ot' construction and ai'- rangement herein setforth, as it obvious vthat various modifications` may be made' therein Without departing' from the .essential eaturcs of the invention as dencd in the appended claims.
